    What SmartwatchRadar is for

    Watch makers quote battery life with the screen dimmed, hide sensors behind brand names and list GPS hours for just one mode. SmartwatchRadar puts every smartwatch, sports watch and fitness band on one spec sheet, so your shortlist lines up row by row and the real differences stand out.

    • Line up to five watches

      Add any two to five watches above and get one table with battery life per mode, GPS, display, health sensors, water rating and smart features side by side.

    • Filter by what you'll use

      The Smartwatch Finder narrows every model by phone, battery life, GPS, maps, health sensors, LTE and brand, so you only see watches that fit.

    • Battery life, mode by mode

      Smartwatch mode, always-on display, GPS, multi-band GPS and solar, each in hours, so a "21-day" claim and a "60-hour GPS" claim can be read side by side.

    • Specs from the makers

      Values come from manufacturer spec pages, manuals and support articles. If a maker doesn't publish a number, the field stays blank rather than holding a guess.

    How to choose a smartwatch

    Seven questions to settle before you buy, starting with the one that rules out the most watches.

    1 of 7

    Start with your phone

    An Apple Watch only works with an iPhone, and most Wear OS and Galaxy Watch models only with Android. Garmin, Amazfit, Coros, Polar, Suunto, Fitbit and WHOOP pair with both.

    Smartwatches for iPhone
    • Replying to messages from the watch is often Android-only on non-Apple watches.
    • Wallet payments depend on the watch and your bank, not just NFC.

    2 of 7

    Decide how often you'll charge

    Full smartwatches with bright screens and apps last one to three days. Sports watches and simpler bands run one to four weeks, and solar models go further outdoors.

    Longest battery life
    • Compare the smartwatch-mode figure first, then GPS hours if you train.
    • Always-on display can cut battery life by half or more.

    3 of 7

    Check how it handles GPS

    Built-in GPS records runs and rides without your phone. Connected GPS borrows the phone's location, so you have to carry it. Multi-band GPS holds a line better near tall buildings and trees.

    Running watches
    • For races and trail runs, look at hours in multi-band mode, not just "GPS".
    • Offline maps matter for hiking, less for road running.

    4 of 7

    Pick the health sensors you want

    Almost every watch tracks heart rate and sleep. ECG, blood pressure, skin temperature and blood oxygen are where models split.

    Health smartwatches
    • An ECG app may only be available in some countries.
    • Some health and recovery reports need a paid subscription.

    5 of 7

    AMOLED, MIP or no screen

    AMOLED screens are bright and colourful but use more battery. MIP screens are easy to read in sunlight and sip power. Screen-free bands skip the display entirely and show everything in the app.

    Screen-free bands
    • Check the case size too: many watches come in two or three.

    6 of 7

    Match the water rating to your plans

    5 ATM covers swimming laps. 10 ATM suits snorkelling and water sports. Diving needs a watch with a dive mode and a depth rating, not just a water rating.

    Rugged smartwatches

    LTE, music and payments

    An LTE version can call, message and send SOS without your phone, but needs a carrier plan. Music storage and wallet payments let you leave the phone at home on a run.

    How we compare: specs you can check, not scores you can't

    Sourced field by field

    Every spec comes from the manufacturer's own pages and datasheets, and we record where each value came from.

    Same yardstick for all

    One spec sheet format for every watch, so a fitness band and a dive computer line up row by row.

    Independent

    We earn from Amazon purchases, never from brands. Read the disclosure.

    Frequently asked questions

    How do I compare smartwatches side by side?

    Type a watch's name into the search box at the top of this page and add it, then add up to four more. You'll get one table with every spec lined up. You can also tick Compare on any watch in the Smartwatch Finder.

    What's the difference between a smartwatch, a sports watch and a fitness band?

    A smartwatch focuses on apps, messages and payments with a bright screen. A sports watch puts GPS, training metrics and battery life first. A fitness band is slimmer and tracks activity, sleep and heart rate, sometimes without any screen.

    Why is the battery life on your sheet lower than on the box?

    The box usually shows the best case, for example with the screen dimmed or a lighter use profile. We record the maker's smartwatch-mode figure and list every other mode they publish, each in hours.

    Do I need a subscription?

    For most watches, no. Some brands keep advanced health insights, coaching or recovery data behind a paid plan, and a few bands need one to work at all. Check the subscription row in the spec sheet.

    Where do your specs come from?

    From manufacturer spec pages, user manuals and support articles. Other sources only fill gaps the maker leaves, and a spec nobody publishes stays blank.
